We were working with a new customer the other day. They had a younger developer helping them out to go live with their infrastructure. He had previously worked with a larger enterprise company in their development area and worked mostly with AWS.
He had asked us for some shared storage between virtual machines and I asked him why he needed this. He explained that when one of the virtual machines goes down, the other one can continue using the same storage. He then explained to me that this happens a lot in AWS.
I had to smile a bit and remind him that he’s in a VMware environment where we are expected to be up 24/7/365. He had heard of VMware but didn’t understand what HA, DRS, vMotion,etc.. was. Once explained to him, he said he could cut the number of virtual machines in half and the deployment would be much easier.
I sent him an uptime from one of our Esxi hosts and he still couldn’t believe it. 989 days and still going strong. He sent it over to some of his friends that continue to work on AWS infrastructure. David vs. Goliath but David has years of uptime…
The ESXi Shell can be disabled by an administrative user. See the
vSphere Security documentation for more information.
